Hello Community!
I have a variable problem with phones of VVX series.
I'm setting up the phone and it works stably. But at some point (for examle, after a month) after talking when you hang up, the phone display freeze. i.e. actually the conversation ended, but the animation on the display continues to operate. Then after day the phone with this problem the phone this problem works properly. What is the reason? How can we solve this problem?
version firemware 5.5.0.20556 on VVX310 and VVX500
